 strise ; legs red, tarsi more or less pitchy, femora clavate, sometimes 

 pitchy at apex ; the colour of the upper surface is very variable, and, 

 except in quite fresh specimens, has a very abraded appearance. 

 L. 5-7 mm. 



Male with the first ventral segment of abdomen impressed, and the 

 second with a transverse fold behind. 



On whitethorn, young trees in woods, nettles, &c. ; generally distributed and common

 distinguished by having the scales smaller and duller, and the antennae 

 with the apex of scape and at least the base of the club dark ; the eyes
